Just dynoed my magnetic drain bolts before and after. Got 8whp gain and 14tq! Let me know if u guys want a dyno graph.
To the op, all seriousness, if you have all that done and tuned properly with lets guess 10psi which usually is around 350-400whp with that log manifold, you should wreck that ecoboost if they really are pushing 300hp at the crank. Shouldnt even be a match actually.
